The bolts 15 correspond 111 number to the entrance of dust and the like.

The present embodlment of the invention of the said bolts. Each spring has its inner end bent to form a ring 17 encircling a bolt comprises a sleeve 1 having its outer end reduced externally and screw threaded at 2, 15. and the said spring is then bent to paran annular shoulder 3 being formed between tially encircle the ring 17 in spaced relathe threaded portion and the body of the tion, and the outer end of each spring is rehub, and the said threaded portion is adaptceived between a bolt 13 and the inner face of the ring 10.

The sleeve iS designe to re ei the transversely, indicated at 18, at each bolt spindle of the axle, and the said sleeve is 13, and the outer end of each of the springs provided near its inner end with an annular 16 i ovid d with a transver e groove 19 rib or enlargement 5, and with radial flang on the inner face of the spring, which forms a transverse rib on the outer face, and each 6 and 7 at each end of the said rib, the

Each flange has its side walls beveled, as

The springs 16 are similar in shape, and are shown in Fig. 2, so that the groove or channel between the flanges for receiving the spokes is of lesser width at its bottom than similarly arranged, and the said springs are between the housing plate 12 and between the flanges 6 and T of the sleeve 1. The

The ring 10 is annularly enlarged or rabsleeve 1 may be thus moved freely radially with respect to the ring 10, within limits beted at each side of its inner face, as indicated at 11, and housing plates in the form of rings 12 are arranged upon each side of prescribed by the springs 16. Bolts 20 are I passed through the flanges 9 of the ring 10 between each pair of adjacent spokes, and

the said ring, the outer edge of each of the said plates fitting within the adjacent rabthe said bolts are engaged by nuts 21 to hold the flanges and the spokes beted portion 11, and bolts 13 are passed through the flanges, at spaced intervals,

in proper relation. 11o

The inner ends of the spokes are curved to fit the outer face of the ring 10, and the bolts 20 and the flanges 9 prevent disengagement of the said spokes from the ring 10.

The device consists in fact of concentric hubs and springs between the hubs normally holding them in spaced relation, to permit the said hubs to yield with respect to each other. T he springs 16 are inserted in their normal shape, Without compression so that the lead on the inner hub will be distributed equally and uniformly among the springs, Which are twelve in number in the present instance, although it is obvious that a greater or less number may be used in accordance with the type of wheel.

1. In combination, a sleeve provided with radially extending flanges intermediate the ends of the sleeve, said flanges being spaced longitudinally of the sleeve, a ring for con nection with the spokes of a wheel, arc springs arr: nged between the hub and the ring, each spring having its inner end arranged between the flanges and secured thereto and having its outer end fitting against the inner face of the ring, means for securing the said end of each spring to the ring, and housing plates connected with the ring at each side thereof and extending inwardl beyond the outer edge of the adjacent flange, the said ring being rabbeted to receive the outer edge of each housing plate, bolts connecting the flanges of the ribs at spaced intervals, each spring having its inner end connected to a bolt, the means for securing the outer ends of the springs to the ring comprising bolts extending through the housing plates at the ring and clamping the said plates to the ring, the outer end of each spring having a transverse groove and the ring having a t'ansverse groove at each of the said bolts for receiving the groove of the spring.

9. In coinbimition, a sleeve having annular radial flanges intermediate its ends and spaced apart from each other, a ring for connection with the spokes of a wheel, are springs arranged between the hub and the ring, each spring having its inner end arranged between the flanges and secured thereto and having its outer end fitting against the inner face of the ring, housing plates arranged at each side of the ring and extending inwardly toward the flanges, bolts extending through the housing plates at the surface of the ring and clamping the said plates against the ring, the outer and of each spring having a transverse groove and the ring having a transverse groove at. each of the bolts for receiving the groove of the spring, to prevent displacement. of the outer end of the spring.
